Scrap & materials: resell it, repair it, part it out or sell the metal?
Four ways to get value from one item. Pick the one that pays for your time.
In short
Most items are worth more whole than as metal. Material recovery only wins when nobody wants the item as it is, the metal is verified, a buyer near you takes it, and the extra hours still pay. This section helps you compare the routes and tells you what you can afford to pay. “Do not buy” and “sell it intact” are normal results.
- The four routes are alternatives. You take one, you do not add them up.
- An item that does not work is not automatically scrap.
- Weight on a listing is not copper weight. Reels, insulation, fittings and steel are in there too.
- A missing resale price means “unknown”, not zero.
- Count your hours. More sale proceeds can still mean less profit.
The four value routes
Every item keeps its category: a cable stays a cable, a motor stays a motor. Which route fits depends on evidence, buyers near you, your skills and your time.
Resell as-is
Someone can use it the way it is. Usable pipe lengths, bar stock and full cable rings often sell above scrap price. Check this first.
Repair and resell
Worth it when the fault is confirmed and the repair is within your skills. See the repair-then-flip guides and calculator.
How repair-then-flip works →Sell useful parts
Some parts are worth more than the rest. A part you sell cannot also be weighed in as scrap.
Recover materials
Sell the metal by weight, as found or after stripping and sorting. Needs verified material, a net weight and a buyer who takes the grade.
Launch profiles
Copper pipe and offcuts
Usable lengths often beat scrap. Fittings and solder lower the grade.
Suitable for beginners
Solid copper bar and sheet
Dense and simple to weigh. Check plating and where it came from.
Suitable for beginners
Copper cable
The copper share and your hours decide. Thin cable is rarely worth stripping.
Suitable for beginners
Tell copper from look-alikes
Do these checks on material you may handle. A photo or a model name can raise a question. It cannot answer it.
| Material | What you see | How to check | Watch out |
|---|---|---|---|
| Copper | Red-brown. A fresh cut or file mark is salmon-pink all the way through. | Not magnetic. Heavy for its size. Cable printing such as NYY or NYM points to copper conductors. | Tinned copper looks silver outside and is a separate grade. |
| Copper-clad aluminium (CCA) | Copper-coloured outside. A cut end or a scrape shows silver-white inside. | Very light. Scrape the strand with a blade. Common in cheap speaker, car-audio and network cable. | Never paid as copper. Buyers pay it as aluminium or refuse it. |
| Aluminium | Silver-white, dull grey when old. | Not magnetic, light. Cable printing starting with NA (NAYY) means aluminium conductors. | Thick “earth cable” is often aluminium. |
| Brass | Yellow. A file mark stays yellow, not pink. | Not magnetic. Typical for fittings, valves and taps. | A separate, lower grade. Do not weigh fittings in as copper. |
| Plated steel | Copper-coloured surface only. | A magnet sticks. A file shows grey steel. | “Copper-coloured”, “copper look” and “copper-plated” mean it is not copper. |
Only cut or file material that is already disconnected and that you may handle. If the seller will not show a cut end, treat the material as unknown.
Grades and price tiers
Metal buyers pay by grade and by quantity. The same copper can fall into different grades at two dealers.
- Insulated cable is paid by its assessed copper share, not as copper.
- Stripped wire is not automatically the cleanest grade. Tinned, oxidised or enamelled wire pays less.
- Quantity tiers count the weight you hand over in that grade, not the weight of the lot you bought.
- Attachments such as solder, fittings, paint or plastic are deducted or lower the grade.
- Brass and aluminium have their own grades and are never paid as copper.
Items for expert assessment only
These can hold metal, and they can be worth far more whole. We help you identify them and ask for quotes. We publish no dismantling instructions and no copper quantities for them, because we have no measured evidence.
Copper hot-water cylinders
Only under conditions
Identify
- Check that the tank itself is copper. Many are steel or stainless steel under the insulation.
- Only cylinders that are already disconnected and drained.
Ask
- Ask the buyer how foam insulation and fittings are deducted.
- Ask whether they take it whole.
Heavy and awkward. Do not remove one from an installation yourself.
Electric motors and generators
Expert assessment only
Identify
- Note the exact model from the rating plate.
- Windings can be copper or aluminium. You cannot see which from outside.
- Most of the weight is steel and cast iron.
Ask
- Check the working or repairable value first. A sound motor usually sells for more than its scrap.
- Ask buyers for their price for whole motors.
Unknown windings get no copper value in our calculator.
Dry transformers and transformer welders
Expert assessment only
Identify
- Dry type only. Note model and rating.
- Windings can be copper or aluminium.
Ask
- Check the resale or repair value first.
- Ask buyers for a whole-unit price.
Capacitors and similar parts can hold a charge. Work on them needs electrical competence. Oil-filled units of unknown age are excluded completely.
Heat exchangers that were professionally decommissioned
Hand over to a specialist
Identify
- Only with paperwork showing a professional removed the refrigerant.
- Usually a copper and aluminium mix.
Ask
- Ask a buyer for a quote for mixed copper-aluminium coolers.
No refrigerant work by yourself, ever. A seller saying “empty” is not proof.
Brass and aluminium
Brass and aluminium are in our grade list so you can price fittings and aluminium cable correctly. They have their own, lower prices. Full guides will follow only when we have evidence worth publishing.
Not for beginners
We never suggest recovering material from these:
- Microwave ovens: the capacitor can hold a lethal charge.
- Tube TVs and monitors: implosion risk, stored charge and leaded glass.
- Oil-filled transformers of unknown age: the oil may contain PCB.
- Fridges, freezers, air conditioners and heat pumps with a sealed circuit: the refrigerant must be recovered by a certified professional.
- Damaged or swollen batteries: fire risk.
- Whole vehicles: end-of-life vehicles go to authorised treatment facilities.
- Dead household appliances: collection and treatment are regulated. Reselling a working appliance is a different thing.
Rules in United States
Only material you may take
- Buy from the owner. Cable on public land, material in a skip or leftovers on a building site belong to someone.
- Only material that is already disconnected. We give no instructions for removing anything from a live installation.
- Never burn insulation and never use chemicals to get at metal. Both are illegal in many places and they poison you.
- Calling yourself an expert in the calculator is a preference. It does not give you a licence.
We have not compiled the waste and scrap-trading rules for United States. Check with your local authority before you buy scrap regularly. German rules are not shown here because they do not apply.
